The Vectra XDR connector gives the capability to ingest Vectra Detections, Audits, Entity Scoring, Lockdown, Health and Entities data into Microsoft Sentinel through the Vectra REST API. Refer to the API documentation: https://support.vectra.ai/s/article/KB-VS-1666 for more information.

Tables Ingested

This connector ingests data into the following tables:

Table Transformations Ingestion API Lake-Only
Audits_Data_CL ✓ ✓ ✓
Detections_Data_CL ✓ ✓ ✓
Entities_Data_CL ✓ ✓ ✓
Entity_Scoring_Data_CL ✓ ✓ ✓

Setup Instructions

⚠️ Note: These instructions were automatically generated from the connector's user interface definition file using AI and may not be fully accurate. Please verify all configuration steps in the Microsoft Sentinel portal.

NOTE: This connector uses Azure Functions to connect to the Vectra API to pull its logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the Azure Functions pricing page for details.

(Optional Step) Securely store workspace and API authorization key(s) or token(s) in Azure Key Vault. Azure Key Vault provides a secure mechanism to store and retrieve key values. Follow these instructions to use Azure Key Vault with an Azure Function App.

NOTE: This data connector depends on a parser based on a Kusto Function to work as expected. Follow these steps for Detections Parser, Audits Parser, Entity Scoring Parser, Lockdown Parser and Health Parser to create the Kusto functions alias, VectraDetections, VectraAudits, VectraEntityScoring, VectraLockdown and VectraHealth.

STEP 1 - Configuration steps for the Vectra API Credentials

Follow these instructions to create a Vectra Client ID and Client Secret.

  1. Log into your Vectra portal
  2. Navigate to Manage -> API Clients
  3. From the API Clients page, select 'Add API Client' to create a new client.
  4. Add Client Name, select Role and click on Generate Credentials to obtain your client credentials.
  5. Be sure to record your Client ID and Secret Key for safekeeping. You will need these two pieces of information to obtain an access token from the Vectra API. An access token is required to make requests to all of the Vectra API endpoints.

STEP 2 - App Registration steps for the Application in Microsoft Entra ID

This integration requires an App registration in the Azure portal. Follow the steps in this section to create a new application in Microsoft Entra ID:

  1. Sign in to the Azure portal.
  2. Search for and select Microsoft Entra ID.
  3. Under Manage, select App registrations > New registration.
  4. Enter a display Name for your application.
  5. Select Register to complete the initial app registration.
  6. When registration finishes, the Azure portal displays the app registration's Overview pane. You see the Application (client) ID and Tenant ID. The client ID and Tenant ID is required as configuration parameters for the execution of Vectra Data Connector.

STEP 3 - Add a client secret for application in Microsoft Entra ID

Sometimes called an application password, a client secret is a string value required for the execution of Vectra Data Connector. Follow the steps in this section to create a new Client Secret:

  1. In the Azure portal, in App registrations, select your application.
  2. Select Certificates & secrets > Client secrets > New client secret.
  3. Add a description for your client secret.
  4. Select an expiration for the secret or specify a custom lifetime. Limit is 24 months.
  5. Select Add.
  6. Record the secret's value for use in your client application code. This secret value is never displayed again after you leave this page. The secret value is required as configuration parameter for the execution of Vectra Data Connector.

STEP 4 - Get Object ID of your application in Microsoft Entra ID

After creating your app registration, follow the steps in this section to get Object ID:

  1. Go to Microsoft Entra ID.
  2. Select Enterprise applications from the left menu.
  3. Find your newly created application in the list (you can search by the name you provided).
  4. Click on the application.
  5. On the overview page, copy the Object ID. This is the AzureEntraObjectId needed for your ARM template role assignment.

STEP 5 - Assign role of Contributor to application in Microsoft Entra ID

Follow the steps in this section to assign the role:

  1. In the Azure portal, Go to Resource Group and select your resource group.
  2. Go to Access control (IAM) from left panel.
  3. Click on Add, and then select Add role assignment.
  4. Select Contributor as role and click on next.
  5. In Assign access to, select User, group, or service principal.
  6. Click on add members and type your app name that you have created and select it.
  7. Now click on Review + assign and then again click on Review + assign.

Installing for testing

i. Log in to the Azure portal using the URL - Azure Portal-Home.

ii. Go to Microsoft Sentinel -> Data Connectors

iii. Click the “import” button at the top and select the JSON file VectraXDR_API_FunctionApp.json` downloaded on your local machine from Github.

iv. This will load the connector page, and the rest of the process will be the same as the Installing for users guideline above.

Each invocation and its logs of the function can be seen in the Function App service of Azure, available in the Azure Portal outside the Microsoft Sentinel.

i. Go to Function App and click on the function which you have deployed, identified with the given name at the deployment stage.

ii. Go to Functions -> Any of our function -> Monitor

iii. By clicking on the invocation time, you can see all the logs for that run.

Note: Furthermore, we can check logs in Application Insights of the given function in detail if needed. We can search the logs by operation ID in the Transaction search section.
